338430 divided by 23 
Let's see how many times 23 fits into 338430.

On to step 1:
3 divided by 23 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 23

On to step 2:
If we divide 33 by 23, we get 1 and a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 23 from 33 and we're left with 10.
Include the next digit (8) from the dividend after 10, then repeat: 108 / 23

Going ahead to step 3:
If we divide 108 by 23, we get 4 and a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Deduct 92 from 108 and we're left with 16.
Take the next digit (4) from the dividend and append it to 16, then repeat: 164 / 23

On to step 4:
23 goes into 164 7 times with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 147.0
Deduct 161 from 164 and we're left with 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 23

Moving on to step 5:
If we divide 33 by 23, we get 1 and a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 1471.0
Subtracting 23 from 33 leaves us with 10.
Bring next digit (0) of the dividend behind the 10 and repeat the process: 100 / 23

Going ahead to step 6:
100 divided by 23 is 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 14714.0
Subtract 92 from 100 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
If we divide 80 by 23, we get 3 and a remainder of 11.
The next digit of our result is 3. 
Result so far: 14714.3
The remainder is 11 after subtracting 69 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 8:
23 goes into 110 4 times with a remainder of 18.
The next digit of our result is 4. 
Result so far: 14714.34
If we take 92 away from 110, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 9:
When dividing 180 by 23, we get 7 with a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 14714.347
The remainder is 19 after subtracting 161 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 10:
190 divided by 23 is 8 with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 14714.3478
The remainder is 6 after subtracting 184 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 11:
When dividing 60 by 23, we get 2 with a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 14714.34782
Deduct 46 from 60 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 12:
23 goes into 140 6 times with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 14714.347826
If we take 138 away from 140, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 13:
When dividing 20 by 23, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 14714.347826
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 14:
If we divide 200 by 23, we get 8 and a remainder of 16.
The next digit of our result is 8. 
Result so far: 14714.34782608
If we take 184 away from 200, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 14714.34782608, with a leftover of 1.6e-08.
